Opfindelsen angår en fremgangsmåde til identificering af fremmedlegemer i landbrugshøstmaskiner, som fx. mejetærsker og grønthøster, ved hvilke afgrøden føres til arbejdsaggregatet via et transportapparat, og tjener til at øge driftssikkerheden.The invention relates to a method for identifying foreign bodies in agricultural harvesting machines, e.g. combine harvesters and green harvesters, through which the crop is fed to the work unit via a conveyor, and serves to increase operational safety.
5 Fra grønthøstere er det kendt (fx. ifølge DE-offentliggørelses- skrift 22 52 595 og 25 52 805) at lokalisere metalliske fremmedlegemer, idet der frembringes et specielt magnetfelt i transportapparatet. Ved passage af et metallisk fremmedlegeme indtræder der en ændring af magnetfeltet. Denne ændring registreres, bearbejdes og føres som styre-10 signal til en stopanordning for transportapparatet eller ledes videre til et advarselsanlæg. Det er ufordelagtigt ved denne løsning, at der til trods for denne lokalisering kan opstå havarier på grund af ikke-metalliske fremmedlegemer, især på grund af sten.5 From green harvesters, it is known (e.g., according to DE Publication 22 52 595 and 25 52 805) to locate metallic foreign bodies, creating a special magnetic field in the conveyor. Upon passage of a metallic foreign body, a change in the magnetic field occurs. This change is recorded, processed and transmitted as a control signal to a stop device for the transport apparatus or passed on to a warning system. It is disadvantageous to this solution that despite this location, accidents can occur due to non-metallic foreign bodies, especially due to rocks.
Af denne grund er der blevet udviklet forskellige mekaniske frem-15 gangsmåder (fx. ifølge DD-patentskrift 110 413), ved hvilke afgrøden i transportapparatet skannes for fremmedlegemer. Disse løsninger har imidlertid store funktionelle ulemper for afgrødens gennemstrømning gennem maskinen og er derfor ikke blevet realiseret i praksis.For this reason, various mechanical methods have been developed (e.g., according to DD patent 110 413), in which the crop in the transport apparatus is scanned for foreign matter. However, these solutions have major functional disadvantages for crop flow through the machine and have therefore not been realized in practice.
Disse ulemper skal elimineres ved hjælp af løsningen ifølge DE-of-20 fentliggørelsesskrift 3213 713. Her registreres lydniveauet på fødeval-sen i transportapparatets stationært lejrede fødevalse, omdannes til elektriske impulser og overføres til en stationær dataregistrerings- og beregningsenhed, som derpå styrer en stopanordning.These drawbacks must be eliminated by the solution of DE-20 Publication 3213 713. Here, the sound level of the feed roller is recorded in the stationary stored feed roller of the transport apparatus, converted into electrical pulses and transmitted to a stationary data recording and calculating unit which then controls a stop device. .
Hed denne løsning registreres ganske vist ikke-metalliske fremmed-25 legemer, men i det tilfælde, hvor fremmedlegemet ligger indlejret i afgrødestrengen og ikke kommer i direkte kontakt med fødevalsen, udebliver identificeringssignalet, hvilket igen kan medføre skade på arbejds-aggregaterne. Samtidig er denne fremgangsmåde omsat til praksis vanskelig at beherske, omstændelig og fejlfølsom, da maskinbetingede lyd-30 svingninger skal holdes fjernt fra lydregistreringsstedet, og signaloverførslen skal finde sted fra en roterende del til et stationært efterfølgende anlæg i en aggressiv omgivelse.Although this solution detects non-metallic foreign bodies, but in the case where the foreign body is embedded in the crop string and does not come into direct contact with the food roll, the identification signal fails, which in turn can cause damage to the working aggregates. At the same time, this method is implemented in practice difficult to master, cumbersome and fault-sensitive, since machine-driven sound oscillations must be kept distant from the sound recording site and the signal transmission must take place from a rotating part to a stationary subsequent plant in an aggressive environment.

identificering af fremmedlegemer skal være særlig stor.foreign body identification must be particularly large.
Til grund for opfindelsen ligger den opgave at tilvejebringe en fremgangsmåde til identificering af fremmedlegemer i landbrugshøstmaskiner med et transportapparat, som fører afgrøden til arbejdsaggre-5 gatet, og ved hvilken fremgangsmåde der benyttes et signal til styring af en stopanordning for transportapparatet eller for et advarselsanlæg, og som klarer sig med få fremgangsmådeskridt, er ufølsom over for støjimpulser fra maskinens side og miljøpåvirkninger og også med sikkerhed registrerer de fremmedlegemer, som er indlejret i afgrødestrengen.The object of the invention is to provide a method for identifying foreign bodies in agricultural harvesting machines with a conveyor leading the crop to the work unit, and in which method a signal is used to control a stop device for the conveyor or for a warning system. and which manages in a few steps, is insensitive to noise impulses on the part of the machine and environmental impacts and also safely detects the foreign matter embedded in the crop string.
10 Dette opnås ved, at a) afgrøden komprimeres vinkelret på sin transportretning, idet et forskydeligt element trykker på afgrøden; b) dette elements accelerationsværdier registreres i komprimeringsret-nin'geri; 15 c) de accelerationsværdier, som er mindre end en reaktionstærskel, slettes, hvorved reaktionstærsklen dannes af de største accelerationsværdier, som opstår ved afgrødens uregelmæssige gennemgang uden indlejrede fremmedlegemer under det forskydelige element; d) de resterende accelerationsværdier, som er større end reaktions-20 tærsklen og stammer fra indlejrede fremmedlegemer i afgrøden, føres som signal til styringen af stopanordningen eller af advarselsanlæg get.This is accomplished by a) compressing the crop perpendicular to its direction of transport, with a displaceable element pressing the crop; b) the acceleration values of this element are recorded in the compression direction; C) the acceleration values less than a reaction threshold are deleted, whereby the reaction threshold is formed by the largest acceleration values arising from the irregular passage of the crop without embedded foreign bodies under the displaceable element; d) the remaining acceleration values which are greater than the reaction threshold and originate from embedded foreign bodies in the crop are transmitted as a signal to the control of the stop device or of the warning system.
Afgrøden mejes eller tages op fra skåret og føres med transportapparatet i sammenført form til arbejdsaggregatet. Under denne trans-25 port komprimeres afgrøden vinkelret på sin transportretning ved hjælp af det forskydelige element, fx. en pressevalse.The crop is cut or taken from the cut and brought to the work unit with the conveyor in combined form. During this transport, the crop is compressed perpendicular to its transport direction by the displaceable element, e.g. a press roller.
Da afgrøden ikke overføres ensartet fra henholdsvis skærebordet eller optageren til transportapparatet, viger det forskydelige element tilbage alt efter afgrødemængden, hvorved der imidlertid samtidig sker 30 en komprimering af afgrøden. Der fremkommer som følge heraf forskellige lave accelerationsværdier for det forskydelige element. Er et fremmedlegeme indlejret i afgrøden, kan dette ikke komprimeres af det forskydelige element, og elementet må inden for en kort tid vige stærkt tilbage. Dermed opstår der en accelerationsspids, som ligger over de 35 normale accelerationsværdier ved afgrøde uden fremmedlegemer. Denne - 3 -Since the crop is not uniformly transferred from the cutting table or recorder to the conveyor, respectively, the displaceable element diverges depending on the crop quantity, however, at the same time, the crop is compressed. As a result, various low acceleration values appear for the displaceable element. If a foreign body is embedded in the crop, this cannot be compressed by the displaceable element, and the element must fall back strongly within a short time. This results in an acceleration peak that is above the normal 35 acceleration values for crops without foreign bodies. This - 3 -

accelerationsdifference er et sikkert tegn pi, at et fremmedlegeme passerer, og benyttes som signal til styring af stopanordningen for trans-portapparatet eller for advarselsanlægget, som det kendes fra metallokalisering.acceleration difference is a sure sign that a foreign body is passing, and is used as a signal to control the stop device for the conveying apparatus or for the warning system as known from metal localization.
5 Til dette er det ifølge opfindelsen hensigtsmæssigt, at kun de ac celerationsværdier registreres, som er større end reaktionstærsklen, og disse omdannes til en elektrisk spændingsimpuls. Dette er muligt, idet accelerations føleren er konstrueret således, at den først reagerer fra accelerationsværdier over reaktionstærsklen. Med henblik på den enkle 10 viderebehandling af signalet er det tilrådeligt straks at omdanne dette til en elektrisk spænding via fx. et induktivt system.For this purpose, according to the invention it is convenient that only the acceleration values which are greater than the reaction threshold are recorded and are converted into an electrical voltage pulse. This is possible since the acceleration sensor is designed to respond first from acceleration values above the reaction threshold. For the simple processing of the signal, it is advisable immediately to convert this into an electrical voltage via e.g. an inductive system.
Ifølge opfindelsen er det imidlertid også muligt, at der i en accelerationsmåler frembringes en med den pågældende acceleration proportional' elektrisk spænding, og denne sammenlignes med reaktionstærsklen, 15 som foreligger i form af en konstant spænding af bestemt størrelse. Den konstante spændings størrelse svarer herunder til accelerationsmålerens spænding, som afgives ved det forskydelige elements største accelerationer ved passage af afgrøde uden fremmedlegemer.However, according to the invention, it is also possible that in an accelerometer an electrical voltage proportional to the acceleration in question is generated and this is compared with the reaction threshold, which is in the form of a constant voltage of a certain size. The magnitude of the constant voltage corresponds to the voltage of the accelerometer, which is delivered by the largest accelerations of the displaceable element when passing crop without foreign bodies.
Med fremgangsmåden ifølge opfindelsen anvises der en enkel løs-20 ning, som er let at realisere, til identificering af fremmedlegemer af alle slags til landbrugshøstmaskiner.The method according to the invention provides a simple, easy-to-realize solution for identifying foreign bodies of all kinds for agricultural harvesting machines.
Denne fremgangsmåde kan realiseres med apparater, som kan indkaps-les godt og afskærmes mod maskin- og miljøpåvirkninger, som fx. en accelerationsmåler og en stationær elektronisk beregningsenhed. Derved 25 er der givet en stor sikkerhed, da alle fremmedlegemer, som kan beskadige arbejdsaggregatet, registreres uafhængig af deres position i afgrøden .This approach can be realized with apparatus which can be well encapsulated and shielded from machine and environmental influences, such as e.g. an accelerometer and a stationary electronic calculator. Thereby, a high degree of certainty is given, since all foreign matter which can damage the work unit is registered independently of their position in the crop.
En yderligere positiv effekt består i, at fremgangsmåden ifølge opfindelsen meget let kan kombineres med de kendte metallokaliserings-30 metoder, idet signalerne fra begge registreringsenheder vurderes fælles, viderebehandles og føres til styringen af en stopanordning. Med denne kombination er der realiseret en alsidig beskyttelse af arbejdsaggregatet, idet selv de mindste metalliske dele yderligere identificeres.A further positive effect is that the method according to the invention can be very easily combined with the known metal localization methods, the signals from both recording units being jointly evaluated, further processed and passed to the control of a stop device. With this combination, a versatile protection of the work unit is achieved, with even the smallest metallic parts being further identified.

udførelseseksempel.embodiment.
På en grønthøster skæres afgrøden af knivbjælken, føres sammen via en tværtransportsnegl og overføres til et transportapparat, som består af flere nedre, stationært lejrede fødevalser og øvre, vinkelret på 5 transportretningen bevægelige fødevalser. De øverste fødevalser forspændes i denne forbindelse i retning mod de nederste fødevalser, således at afgrøden komprimeres mellem de øverste og nederste fødevalser.On a green harvester, the crop is cut by the cutter bar, brought together via a transverse auger, and transferred to a conveyor consisting of several lower, stationary-mounted food rollers and upper, perpendicular to the transport direction, movable food rolls. In this connection, the top food rolls are biased towards the lower food rolls so that the crop is compressed between the top and bottom food rolls.
Alt efter overført afgrødemængde viger de øverste fødevalser tilbage opad, da modtrykket tilnærmelsesvis forbliver konstant. Denne undvi-10 gelsesbevægelse sker relativt langsomt, da afgrøden kan komprimeres stærkt. Tages der et fremmedlegeme, fx. en sten, op af skærebordet, indlejres dette i afgrøden. Kommer dette afgrødeafsnit ind i området under den første øverste fødevalse, undviger denne slagagtigt, da fremmedlegemet ikke kan komprimeres.Depending on the amount of crop transferred, the top feed rollers recede upward as the backpressure remains approximately constant. This avoidance movement occurs relatively slowly, as the crop can be highly compressed. If a foreign body is taken, e.g. a stone, up from the cutting table, embeds this into the crop. If this crop section enters the area under the first top food roller, it avoids slaughter as the foreign body cannot be compressed.
15 Til identificering af fremmedlegemet registreres denne første øverste fødevalses accelerationsværdi i komprimperingsretningen. Hvis et fremmedlegeme passerer, er accelerationsværdien større end ved passage af en ophobning af ren afgrøde. Registreringsenheden er i denne forbindelse konstrueret således, at den først reagerer, når denne stør-20 ste accelerationsværdi for den rene afgrøde overskrides. De registrerede accelerationsværdier, som kendetegner fremmedlegemet, omdannes til et elektrisk signal fx. via feltstyrkeændringen i et induktivt system.15 To identify the foreign body, the acceleration value of this first top food roll is recorded in the compression direction. If a foreign body passes, the acceleration value is greater than when passing a clean crop accumulation. In this regard, the recording unit is designed to respond only when this greatest acceleration value for the clean crop is exceeded. The recorded acceleration values which characterize the foreign body are converted into an electrical signal e.g. via the field strength change in an inductive system.
Dette elektriske signal ledes videre til en dataregistrerings- og beregningsenhed, til hvilken signalet fra en metallokalisering er koblet 25 parallelt dermed. Denne dataregistrerings- og beregningsenheds udgangssignal styrer derpå en stopanordning for transportapparatet.This electrical signal is passed to a data recording and calculating unit to which the signal from a metal location is connected in parallel therewith. The output signal of this data recording and calculating unit then controls a stop device for the transport apparatus.
Der findes imidlertid også den mulighed, at alle accelerationsværdier straks omdannes til ækvivalente elektriske spændinger, som føres til dataregistrerings- og beregningsenheden. I dataregistrerings- og 30 beregningsenheden frembringes der en konstant sammenligningsspænding, som er ækvivalent med den største accelerations værdi ved ren afgrøde uden fremmedlegemer. Alle indgående spændings impulser, som ligger derunder, slettes, de resterede viderebehandles til styring af stopanordningen og ledes til denne.However, there is also the possibility that all acceleration values are immediately converted into equivalent electrical voltages which are fed to the data recording and calculating unit. In the data recording and calculating unit, a constant comparative voltage is produced which is equivalent to the largest acceleration value for pure crop without foreign matter. All incoming voltage pulses located below it are deleted, the remaining are processed to control the stop device and are routed to it.
